provements in l/Vindow-Raising Devices, of

which the following is a specification, refer.

. ence being had therein to the accompanying drawings.

, This invention relates to a mechanically operated window andhasspecial reference l `to a device that may be advantageously used forraising and lowering a sash relative to a frame, particularly thosesashes housed Within the side walls or panels of an automobile body ordoor and adapted to be `raised relative thereto to close the sideA of anautomobile vbody or provide a panel or window on th L.upper edge of anautomobile door.

The primary object of my invention is to `provide simple and effectivemeans that may be easily and quickly installed in the wall of anautomobile body or a door body to safely raise and lower the windowsash, the sash being automatically swung into and out of engagement withthe window frame without any danger of the sash becoming accidentallydisplaced. v r Another object of my invention is to 'provide a sashraising an lowerin device that may be bodily installed and bot ilyremoved from the wall o1' door of an, automobile body, and this isaccomplished without disturbing or removing any part oli the autoymobilebody or door.

' A still further object of my invention is to provide awindow sashraising and low-u ering mechanism wherein the parts are conet@ structedwith a view of reducing the cost of 50 ing, whereininanntacture and atthe same time retain those features by which safety. durability, `easeof operation, and applicability to variious types of motor vehicles aresecured.

. se Withsuch ends in `view m invention resides in the novelconstruction, combination and arrangement of parts to be hereinafter.specifically described and then claimed.

` Reference will now loe-'had to the drawlligure l is a verticalsectional view of a portion ci' an automobile door provided 'with thesaslroperating mechanism;

Figs. 8 and 9 arel detail views of a linlr oi a chain forming p'art ofthe operating mechaanism and l v IFig. 1l is a plan of the same.

Considering the main views of the drain ing, there is shown in Fig. l aportion et a door frame' having an linner wall l and lan outer wall 2aiiiordinp; space or iocltet 3,

ame; y Fig. 6 1s a side elevation of a detachedr Fig. l0 is a frclntelevation ola sash linie;

for a sash, glassplateor panel 4l. The sash is adapted to be completelyhoused within the pocket 3 and the lower rail et said has a hook member5 `adapted 'to a bracket G, carried by the upper inner edge of the outerwall 2, so thatv the s. sli il n' be supported in a raised out of thepocket 3.

The mechanism employed for raf Sill,

2 .c 7 disposed in parallelism with the .inner of the walll andsupported relative the" by a flange 8 at the upper of th Vhanger platesecured on the upper ede'e o the inner wall l. VThe hanger plate' largecentral' opening with the mail ninal. edges of the opening learned eroutturne provide an annular ball race 9, and at ine same time this ballrace is formed7 teeth lll are provided circumferentially of the ballrace and on ther inner. Wall tliereoi", as best .ble CD shown in Fig. 3,said teeth constitutim@` a stationary clutch member.

4In the ball race member il balls or anti-frictional members ll and onsaid balls is an outer rotatable ball race member l2 having flanges 13'connected by screws lller other fastening means to' pin Wheel 15, saidwheel having equally 16 contiguous to the periphery thereof.

The outer ball race member l2 has a eenu trai opening 17 alining witlianopening; iii in the inner wall l of the door frame.

5 or elevated pesition spaced pins orstuds tending through the opening18 and fitted in the opening 17 is an operating shaft 19. Un the outerend of the shaft 19 is a semispherical ball member 20 engaged by asocket member or face plate 21 suitably secured to the Wall 1. A handleor crank 22 on the end of the shaft 19 permits of this shaft beingeasily rotated and said handle or crank is formed with a shield 23 toexclude dirt and other foreign matter that might interfere With themovement of the ball member 2O in the socket `member 2l.

- On the operating shaft 19 adjacent the outer ball race member 9, is apresser member 24 having sockets 25 for balls or detents 26. These ballsor detents 26 are adapted. to extend into recesses 27 in a circularlocking member 28 having a beveled toothed periphery 29 adapted toengage the teeth 10 of the hanger plate 7 and prevent accidentalrotation of the pin Wheel 15. The locking member 28 is formed withcupped portions 30 containing guide pins 31 and coiled compressionsprmgs 32, said springs maintaining the locking member 28 normally inengagement With the hanger plate 7, and through the medium of thedetents or balls 26 holding 'the pin Wheel against accidental rotation.Rotation of the operating shaft 19 cause the detents or balls 26 to rideout of the recesses 27 of the locking member 28 vthereby pressing thelocking member toward the Wall 1 and out of engagement with the hangerplate 7, thus permitting of the pin wheel 15 being freely revolved. Itis therefore apparent that the presser member 24, detents 26 'andlocking member 28 c0nstitute means for holding the pin wheel againstaccidental rotation.

Attached to the pin Wheel 15 and adapted to be trained about the pin orstud 16 thereof is a chain composedv ot' links 33, 3st, 35 and 36. Thelink 33 is pivotally connected to the pin Wheel 15, as at 37, and all ofsaid links are. articulated by connections corresponding to rule joints,so that the joined links can only break in one direction, that of beingtrained about the pins or studs 16 of the Wheel 15. Contiguous to thejoints of the links of the chain are notches or recesses 38 to receivethe pins or studs 16, anda curved guard 39, carried by the hanger plate7, will cooperate with the pins 1G in preventing the links thereon frombecoming accidentally displaced. The link 35 has a rule joint connectionwith the link 36 employed for sup'- porting the sash Ll, and thisparticular link has a longitudinal slot 40 to receive a pin or studr L11of the sash 4l. The sash link 86 is normally held at a right angle tothe link 35 and said link has a cam portion L12 adapted to engage theouter ball race member 12, when the sash is raised, so that said sashwill be forced outward and the hook member 5 Lacoste placed over thebracket 6 of the outer Wall 2. To prevent a sudden descent of the sash 4and cushion a lowering movement of the same, a spiral spring 113 isarranged'betwecn the outer ball race member 12 and the locking member28. The inner convolution of the spring 43 is connected to the lockingmember 28, and the outer convolution thereis accomplished Withoutdisturbing the side Walls 1 and 2 of the door frame.

It is thought that the operation and utility of the sash operatingmechanism Will be apparent without further description,l and While inthe drawings there is illustrated a preferred embodiment of myinvention, it is to be understood that the structural elements aresusceptible to such variations and modiications as fall Within the scopeof thel appended claims.

What claim isz- 1. Means adapted for raising and lowering a sash,comprising a hanger plate having an opening with the Walls of theopening toothed, a revoluble pin Wheel carried by said hanger plate, acircular locking member having peripheral teeth held normallyinengagement with the teeth ot' said hanger plate and adapted to beshifted out of engagement therewith by rofitive movement of said pinWheel to release said pin Wheel, a detachable operating shaft for saidpin Wheel, a link chain having rule 'oints between the links thereof andone o said links connected to said pin wheel with the other linksdisposed to be 'trained on said pin wheel, and a-sash carrying linkforming right angles to one end of said chain? part of said chain andnormally-disposed at 2. The combination with a frame having l a sashpocket, and a sash in the pocket adapted to be raised and lowered, ofsash operatingmeans in the frame pocket and bodily removable from theupper end of the pocket, said means including a hanger plate having anopeningv surrounded by a ball race and the inner Wall of the ball raceprovided ivith teeth, a revoluble pin wheel having a ball race,anti-frictional bearings in the ball races of said pin wheel and saidhanger plate, a detachable operating shaft for said.v
